Mean arterial blood pressure can be regulated by changing which of the following?
I.capacity of the circulatory system
II.effective volume of circulating blood
III.tone of the capacitance vessels (veins)

Question

Quizplus · Accepted Answer

Mean arterial blood pressure can be regulated by changing the capacity of the circulatory system, the effective volume of circulating blood, and the tone of the capacitance vessels (veins). For example, increasing the effective volume of circulating blood by increasing fluid intake or decreasing urine output can increase blood pressure. Similarly, constricting capacitance vessels can increase peripheral resistance and raise blood pressure. Therefore, all three choices are correct.
